In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - on ground/water, takeoff - roll/run
  - directional control - not maintained, pilot in command (cause)
  - weather condition - crosswind (contributing factor)

- Main gear collapsed, landing
  - aborted takeoff - performed, pilot in command

## Analysis

AS PLT INITIATED TAKEOFF IN A LEFT X-WIND, ACFT BEGAN TO WEATHERVANE TO THE LEFT. INCREASED RIGHT RUDDER AND REPEATED APPLICATIONS OF RIGHT BRAKE FAILED TO ARREST AN INCREASING SWERVE TO LEFT, WITH RIGHT BRAKE PEDAL EVENTUALLY BOTTOMING OUT. AS ACFT DEPARTED RUNWAY SURFACE IN INCIPIENT GROUNDLOOP, PLT REDUCED POWER AND 'RODE IT OUT.' THE RIGHT MAIN GEAR COLLAPSED DUE TO EXCESSIVE SIDE LOADS IN ROUGH TERRAIN. PLT CITED LACK OF INFORMATION IN ACFT MANUAL CONCERING USE OF TAIL WHEEL LOCK FOR CROSSWIND TAKEOFF. INVESTIGATION REVEALED NO PRE-EXISTING DEFECT WITH BRAKE SYSTEM.
